Andorra (France)

Postal services in Andorra are unique in that they are not operated by the country itself, but by its two larger neighbouring countries, Spain and France.[1This is a legacy of the centuries of de facto control exercised by those two countries over Andorra. Correos of Spain and La Poste of France operate side by side.

However the postal code system, introduced in July 2004, has a different format from those of either Spain or France, consisting of the letters "AD", followed by three digits.
